Recent fMRI and EEG research for neural representations of action concepts insist that processing of action concepts evoke the simulation of sensory-motor information. Moreover, there are several behavioral studies showing that understanding of action verbs or sentences describing actions interfere or facilitate current action performance. However, it is unclear that online interaction between processing of action concepts and current action is based on the simulation of sensory-motor information, or other neural mechanisms. The present research aims to explore the underlying neural mechanism that how the perception of action language influence the performance of current action using high-spacial temporal resolution EEG and multiple source analysis techniques. For this, participants were asked to perform a cued-motor reaction task in which button-pressing hand action and pedal-stepping foot action were required according to the color of the cue, and we presented auditorily action verbs describing the responding actions (i.e., /press/, /step/, /stop/) just before the color cue and examined the interaction effect from the semantic congruency between the action verbs and the current action. Behavioral results revealed consistently a facilitatory effect when action verbs and responding actions were semantically congruent in both button-pressing and pedal-stepping actions, and an inhibitory effect when semantically incongruent in the button-pressing action condition. In the results of EEG source waveform analysis, the semantic congruency effects between action verbs and the responding actions were observed in the Wernicke's area during the perception of action verbs, in the anterior cingulate gyrus and the supplementary motor area (SMA) at the time when the motor-cue was presented, and in the SMA and primary motor cortex (M1) during action execution stage. Based on the current findings, we argue that perceived action verbs evoke the facilitation/inhibition effect by influencing the expectation and preparation stage of following actions rather than the directly activating the particular motor cortex. Finally we discussed the implication on the neural representation of action concepts and methodological limitations of the current research.

This study was aimed to investigate the motivators of smoking in 300 subjects using convenient extraction in one hospital. After informed consent, the survey that consisted of general characteristics, health behavior, stage of change, health behavior-related-perceived benefit, health behavior-related-perceived barrier, health behavior-related-family support, oral health behavior, subjective oral health and others was carried out. The smoking rate was higher in case of male (sex), high school graduates (education) and 2~3 million Korean won (KRW) (monthly income). The present smokers responded lower oral health behavior (p<0.001), lower health behavior-related-perceived benefit (p=0.021), higher health behavior- related-perceived barrier (p<0.001) and lower stage of change (p<0.001). The oral health related variables were not influenced by smoking. In logistic regression model, odds ratios in smoking were 0.378 in below average (health behavior-related-perceived barrier), 4.746 in below average (stage of change), 12.743 in male (sex) and 3.271 in 2~3 million KRW (monthly income/standard : over 3 million KRW). It was suggested that oral health related manpower should take account of not only smoking-related oral health but also motivators of smoking as to deliver effective no-smoking program.

This study aimed to examine the mechanisms underlying digital game usage behavior by applying the Theory of Planned Behavior and the Balance Theory. It investigated the influences of attitude, subjective norms, and perceived behavioral control on the intention to use digital games, as well as the differences in the application of the Theory of Planned Behavior model based on the balance state among individuals, significant others, and digital games. A total of 315 responses from adult PC game users were collected through an online survey conducted from October 21 to 25, 2021, and were analyzed using multiple regression analysis. The results revealed that attitude and perceived behavioral control had a significant positive impact on the intention to continue using digital games, while subjective norms did not exert a significant influence. By categorizing groups into balanced, unbalanced, and imbalance states based on the balance relationship, the application of the Theory of Planned Behavior model showed that in the unbalanced and imbalance groups, both perceived behavioral control and attitude had a positive impact on the intention to continue using digital games. However, in the balanced group, attitude only had a positive impact on the intention to continue game usage. This study contributes to understanding digital game users by examining both individual psychological factors and the influence of others on digital game usage behavior.

The purpose of this study is to identify the factors affecting female college students' behaviors in seeking reproductive health information on the Internet and to explore the relationships among these factors. Based on the Health Belief Model(HBM) and the Theory of Planned Behavior(TPB), perceived sensitivity, perceived severity, perceived benefit, perceived barriers, subjective norms, perceived behavioral control, and affective evaluation were defined as key factors, and the study was designed accordingly. An online survey was distributed to female college students in Seoul through the university student's online community, 'Everytime.' The results showed that the intention of female college students to seek reproductive health information via the Internet was associated with higher perceived sensitivity, perceived benefit, and subjective norms, and lower perceived barriers. There were statistically significant differences between groups in terms of sexual experiences, experience with reproductive system disorders, and the level of health interest. We believe that this research outcome will contribute to assessing the level of awareness regarding reproductive health among female college students, thereby aiding in the development of online health information literacy education or related service programs by university libraries, health institutions, and similar entities targeting female college students.

The rapid development of information and communication technology has made it for people to pirate digital contents easily and quickly. Although many studies have investigated the underlying factors that lead to an individual engaging in digital piracy, few studies have provided holistic and integrative view on this issue. Therefore, this study attempts to build integrative research model based on theory of planned behavior (TPB), norm activation model (NAM), and habit. For this purpose, this study develops nine hypotheses that explain the relationship between attitude, personal norm, habit, and behavioral intention, and tests them with survey data collected from 337 participants. The results of this study show that attitude, perceived behavioral control, personal norm, and habit have impact on behavioral intention of digital piracy while subjective norm does not affect behavioral intention. This study contributes to expand existing studies by identifying the relationship between attitude, personal norm, habit and behavioral intention.
